Question

part a
of the four fundamental forces presently known, the force of gravity is
view available hint(s)
hint 1.
check the value of the universal gravitational constant, g.
the weakest
the same as the others
always downward
the strongest

Explanation:

Among the four fundamental forces (gravitational, electromagnetic, strong nuclear, and weak nuclear), the gravitational force has an extremely small coupling constant. The universal gravitational constant G is very small ($G = 6.67\times 10^{- 11}\ N\cdot m^{2}/kg^{2}$), making gravity the weakest of the fundamental forces.

Answer:

A. the weakest
